Two-factor authentication in combination with Exchange Active Sync


we are planning to use two-factor authentication for logins on our Windows 2012 domain using hardware tokens. But how does this reflect on the use of Exchange Active Sync on smartphones? Will that still work and how? Do smartphone users need to complete the two-factor authentication everytime they want to sync their mailbox?
Or can you exclude Exchange Active Sync from the two-factor authentication some how?
We use Exchange 2010.

Typically as long as the device wasn't disconnected / timed-out there is no need to input the second factor authentication again

now if your mobile device will support it or not will depend on the device & the solution itself and your gateway, you could also exclude the EWS and ActiveSync virtual directories also depending on your specific solution
